Alttab on mobile devices

Alttab runs on every device that can run X11.

It's trivial with Linux phone (Pinephone, Librem, Pro1-X, Volla).

With Android, alttab runs fine in Linux chroot displaying in XServer XSDL.

Touchscreen control

Using -e option, an external program can pop up the switcher:

alttab -e &
xdotool key alt+Tab

This is particularly useful with Linux phone and gesture daemon. To call alttab by swipe to the right at the left screen edge:

alttab -mk Control_L -e &
lisgd \
    -g '1,LR,L,*,/usr/bin/xdotool key ctrl+Tab' \
    ...other lisgd options... &
